Arsenal lose 'Ox' for 3-4 weeks

London - Arsenal manager Arsene Wenger says Alex Oxlade-Chamberlain will be out for up to four weeks with a hamstring injury, which is set to rule the midfielder out of two upcoming England games.

Oxlade-Chamberlain, who recently returned to the Arsenal team, pulled up with the injury during Arsenal's 2-1 win over Manchester United in the FA Cup on Monday.

Wenger says the 21-year-old Oxlade-Chamberlain will be out for "three weeks, four weeks maximum."
